According to Newsweek, approximately 600 al-Qaeda and Taliban fighters, including many senior leaders, escape Afghanistan on this day. This is the first day of heavy bombing of the Tora Bora region (see November 16, 2001). There are two main routes out of the Tora Bora cave complex to Pakistan. The US bombs only one route, so the 600 are able to escape without being attacked using the other route. Hundreds will continue to use the escape route for weeks, generally unbothered by US bombing or Pakistani border guards. US officials later privately admit they lost an excellent opportunity to close a trap. [Newsweek, 8/11/2002] On the same day, the media reports that the US is studying routes bin Laden might use to escape Tora Bora [Los Angeles Times, 11/16/2001] , but the one escape route is not closed, and by some accounts bin Laden and others escape into Pakistan will use this same route several weeks later (see November 28-30, 2001). High-ranking British officers will later privately complain, “American commanders had vetoed a proposal to guard the high-altitude trails, arguing that the risks of a firefight, in deep snow, gusting winds, and low-slung clouds, were too high.” [New York Times, 9/30/2002]
